ASSIG-NOB, BY DIRECT AND MESNE MULTIPLE-MAGAZINIE-CHANGING DEVICE FOR CHANGING SPLIT MAGAZINES ON TYPESETTING MACHINES.

Application filed May 24, 1924. Serial No. 715,533.

To all whom it may concern:

Be it known that I, HERMAN T. Sena STHOM, a citizen of the United States, residing at Houston, Texas, have invented a certain new and useful Improvement in Multiple- Magazine-Changing Devices for Changing Split Magazines on Typesetting Machines, of which the following is a specification.

My invention has reference to machines of the general organization represented in Lettors Patent of the United States to Ottmar lifergenthaler No. 436,532 and commonly known in the art as linotype machines. In these machines circulating female type or matrices representing the various characters are discharged from the channeled magazines in which they are stored and assembled in line in the order in which the characters are to appear in print, together with spacers between the words, and the composed line transferred to close the face of a slotted mold into which metal is pumped from a melting pot to form the slug or linotype, on the front edge of which the matrices form the characters to print a line.

As ordinarily constructed, the magazines of these machines are of such length that one channel will contain a large number of matrices, usually twenty or more of the lower case vowels, a number of which will appear on a slug in long lines of print. When large type for advertising or other purposes is to be produced on the slugs a smaller number of matrices will answer, since the slug will contain but a small number of each character. For this reason the fonts for large characters contain a much smaller number of matrices than the others, and such fonts can be stored in magazines shorter than those required for text characters. For this reason, and to permit the speedy substitution of one font for another, that the machine may produce a variety of display or advertising matter, it is customary to divide the long magazines, which remain on the machines, transversely midway of their length, or thereabouts, as shown, for example, in Letters Patent of the United States Nos. 1,136,534; and 1,367,606, both islected magazine in sued to D. S. Kennedy, so that the lower end or section is capable of receiving a font of display matrices. This lower section may be safely and easily removed and replaced by another.

The object of my invention is to adapt the machine to receive a substantial number of these short magazines and to provide for the instantaneous mechanical substitution of one for another in the operative position; in other words, to secure the practically instantaneous substitution of one magazine and font for another. To this end I provide a machine, which may otherwise be of any ordinary or suitable construction, with means for sustaining a plurality of small magazines in an inoperative position and for removing from the operative position one magazine and replacing it with one of the others. In the mechanism herein shown manually operated devices lift the magazine which is in operative positionbodily and thrust it endwise into an elevated rack or holder. The mechanism serves also to withdraw any other selected magazine endwise from the rack or holder and lower it to the operative position on the machine. In brief, the mechanism permits the practically instantaneous substitution of any seplace of the one previously in operative position.

Other objects and advantages of the in vention will become apparent from a more detailed description which follows:

Referring to the drawings herewith wherein an embodiment of my invention is disclosed in such form as to be applicable to a linotype machine, Fig. 1 is a side elevation of a linotype magazine frame and escapement showing my invention applied thereto, the parts constituting the invention being shaded somewhat. Fig. 2 is a broken detail of the magazine latch and the lever pawl adjacent thereto, parts being broken away for greater clearness. Fig. 3 is a rear elevation of the operating mechanism; Fig. 4 is a top plan view of the magazine frame and rack; Fig. 5 is an enlarged detail of the lock mg mechanism seen from the front side of the machine, and Fig. 6 is a broken detail partly in section on the line 6-6 of Fig. 5. Like numerals of reference are employed to designate like parts in all the views.

It is to be understood that the ordinary linotype machine is provided on the right hand of the operator with a magazine frame and escapement capable of handling one magazine of matrices at a time, and in the drawings my invention is shown as being applied to a linotype machine having the customary magazine frame thereon. Referring particularly to Fig. 1, the main intermediate bracket 1 of the linotype machine is shown as furnishing a base for the escapement support bracket 2 thereon at the upper end of which is secured an inclined magazine frame 3. At the lower end of the frame upon the escapement support bracket 2 is the cscapement mechanism 1. It is to be understood that magazines ordinarily resting on the frame 3 will bear at the lower end against the escapement mechanism f, and that matrices will be fed through the operation of the escapement mechanism to the machine when the magazines are un locked by removing the matrix retaining rod which is employed in the old device to lock the magazine until ready for use. The escapemcnt mechanisn'i 4.- is actuated as usual by a keyboard mechanism- (not shown) in effecting the release of the matrices from the magazine in operative position.

In order to store the magazines in convenent position upon the magazine frame, 1 rovide a rack 6 at the upper end of the said irame. The said rack consists of two side plates, one on each side of the magazine frame, held firmly in spaced relation by cross bolts 7 at the rearward upp r ends thereof. The lower sides are secured to the frame by means of set screws, or any other desirable means. Both of the opposite plates are provided with a plurality of slots 8 extending from the forward end rearwardly a sufficient distance to accommodate the supporting pins on the sides of the magazines. Each of the magazines has, on directly opposite sides thereof, rearward pins 9 which are of such length as to extend flush with the outer faces of the plates 6. The forward pins 10 on the magazine extend through the slots a sufficient distance to be engaged by latches or pawls 11 mounted on the two side plates of the rack 6. Each latch is pivoted upon a pin 12 at its rearward end, and has a lower pointed end 13 to engage over the pin 10. Above the latch portion 13 on the outer side of the pawl, is a cam member 14, the lower and rearward faces of which are inclines. downwardly to a point. As will be later noted, these cam surfaces thus provided, enable the operat ing lever to latch or unlatch the magazines when it isdesired to move them. The latches are held downwardly into latched position by springs 16 at the side of the rack, and the movement of the dogs downwardly is limited by stop pins 17, mounted on side plates 6 and fitting in slots in the lower sides of the dogs.

To move the magazines from the storage racks 6 into operative position below said rack upon the magazine frame, I have provided an elevator frame 15. The said frame consists of two side plates 18, the lower ends of which are slotted at 19 to receive the cross rod 20 upon which the frame is slidable. Said frame is mounted in a position with the upper end inclined forwardly to place it at right angles to the magazine frame 3. The lower ends of the plates 18 are secured together in spaced relation by a cross bar 21, the rearward side of which, as shown in Fig, 3, is flattened so as to provide engagement for a latching bar 22, which is pivoted on a cross rod or shaft 20 at its upper end, and is pressed by gravity against the bar 21. Its forward face is provided with a plurality of notches 24 spaced a predetermined distance apart to support the elevator frame as will be later described.

The upper end of the elevator frame has thereon a lifting rack 25. This rack has two spaced side plates secured to said frame and extending rearwardly into contact with the forward face of the magazine rack. This said lifting rack is slotted at 26 from its rearward end to a point spaced slightly back of the forward end thereof, and provides a supporting seat for the two pins 9 and 10 upon the sides of the magazines. It will be obvious that the magazines from the rack may slide by gravity downwardly into the slots 26 when the elevator frame is in proper position.

The rod 20 fitting in the slot 19 is supported upon a frame 27 comprising two side plates secured to the lower end of the intermediate bracket of the linotype, and extending upwardly in an inclined position to support the rod 20 at the upper end of the slot 19 when the elevator rack is in its lowest position. The elevator is raised and lowered from the position shown in Fig. 1 to the different positions whereby the slot 26 in the elevator rack is brought into registration with. the slots 8 in the magazine rack by an operating mechanismwhich will now be described.

Supported from the lower ends of the plates 27 are two hangers 28. These hangers furnish support for the opposite ends of two transverse shafts 29 and 30, each of which is provided at one end outside of said hangers with gears 30 which mesh together so that the rotation of the lower shaft will cause the rotation of the upper shaft, in the opposite. direction. There is a hand lever 31 on the shaft 29 which by movement in an llitt are about said shaft will thereby rotate shaft in a direction opposite thereto. Fixed upon the shaft 30 at its opposite ends '(Fig. 3) are the elevator levers 32. These levers project rearwardly and have pivotal connection at 33 with the arms 34 which connect the elevator levers with the pins 35 which form a pivotal support therefor upon the elevator frame 18 at a point about midway between the ends of said frame.

It will be obvious therefore that the raising and lowering of lever 31 will serve to move the elevator frame upwardly and downwardly as desired, so as to bring the elevator rack into proper position to engage and receive the magazine desired. Pivoted upon the cross shaft 20 on each side of the elevator frame is a U shaped latching member 36. This latch bar is held by gravity against the rearward edge of the elevator frame and said edge is provided with spaced notches 37 to receive the latch whereby the elevator frame may be held in proper position to register with the slots 8 in the magazine rack. There will be as many of the notches 37 as are necessary to hold the elevator rack in the different positions required to receive the magazines from the magazine rack. This latch may be moved from latching position, when desired to move the elevator frame, by means of a rod 39 connected with a hand lever 40 on the operating lever 31, said rod being connected at its opposite end to an arm 41 by being hooked into an opening therein and forming a pivotal engagement therewith. Said lever 41 is pivoted between its ends upon a pin 42 on the frame 27, and having a laterally projecting pin 43 at its opposite end engaging against one Side of the U shaped latching bar. It will thus be obvious that by pressing the lever 40 the lower end of the arm 41 will be drawn forwardly, thus pressing the pin 43 against the latching arm and raising it from its position within the slot 37.

When the elevator frame has been raised into adjusted position to receive or deliver a matrix magazine from or to the rack 6, as

shown in dotted lines in Fig. 1, operating means is provided to handle the magazine without the necessity of the operator leaving his seat. This is done as follows: To the lower end of the elevator frame 18 on the K V rearward side thereof are opposite bearing blocks 45. These blocks support a shaft 46 which is rotatable therein. Said shaft has fixed thereto on the end adjacent the lefthand of the operator a downwardly extendmy; arm 47 which may be operated by a sliding bar 48 extending forwardly to a point adjacent the operator and having a handle 49 thereon. Secured on shaft 46 are two opposite upwardly extending lever arms 50,

. one at each side of the elevator frame and extending to point slightly above the lifting rack 25 of said elevator, as shown in Fig. 1. Pivoted at the upper ends of the magazine operating levers 50, are two for wardly extending pawls or fingers 51. Said fingers are curved downwardly and hooked at 52 to engage loosely about the lower pins 10 upon the matrix magazine. As shown in Fig. 2, each finger has at the forward end and extending inwardly therefrom, a pin 53 which governs its movement when moving the magazine into latched position in the rack.

Supposing the elevator to be raised into dotted line position with a matrix magazine therein, as shown in full line position, the magazine would be thrown back into the magazine rack by pulling sufficiently on the lever handle 49, thus throwing the lever arms 50 to the rear, sliding with it the magazine, the pins 9 and 10 of which will be received within the adjacent slot 8 of the rack. The pins 10 project beyond the elevator frame to engage beneath the points 13 of the latches 11, forcing them upwardly to allow the pins to pass beyond the same. When thus latched in position, the pins 53 upon the fingers 51 will engage with the rearward faces 14 of the latching pawls, and thus carry the fingers upwardly away from the pins 10, and thus allow the arms 50 to be moved back away from the magazine. The elevator can then be readjusted to bring the slot 26 therein into registration with another of the slots 8 in the magazine rack to receive another of the stored magazines. To unlatch and move the new magazine into the elevator rack, the lever arms 50 will be again operated to move them rearwardly and in doing so, the pins 53 on the inner side thereof will engage on the lower cam faces of the latches 11, thus moving them upwardly so as to release the pins 10 where by the force of gravity will cause the magazine to slide from the rack, and as it is released from the latch the hooked ends of the fingers 51 will engage the pins 10 upon the magazine, and the operator can then move the lever to allow the magazine to drop slowly into position upon the elevator rack. When in proper position, the elevator may be lowered into the full line position shown in Fig. l by means of thelever arm 31, as previously described.

In order to prevent the elevator frame from moving from its position while the operating arms 50 are thrown back to engage the magazine rack, as shown in dotted lines at 50 in Fig. 1, the safety latch 22 is provided. This latch, as previously described, is pivoted upon the shaft 20 and depends downwardly therefrom and is held by gravity against the lower side of the bar 21 upon the elevator frame.

A dog 54 is fixed centrally upon the shaft 46 adjacent the safety member 22, and has a laterally extending pin. 55 thereon engaging on the lower face of said safety member. l/Vhen the shaft 16 is rotated from the turn of the hand lever l9 to throw the magazine engaging levers rearwardly, it will release the safety bar-22 so as to allow one of the notches 2a therein to engage with the lower end of the bar 21 of the elevator frame, and thus hold the frame in the position it was when the shaft 46 was rotated. hen the arms 50 have been moved back into the position shown in Fig. 1, the pin on the dog 5% will engage beneath the safety member 22 and raise it so as to allow the frame to be moved again into a newly adjusted position.

In order to do away with the matrixretaining rods ordinarily employed with thematrix magazine, and also to allow the automatic locking and unlocking thereof, each of the magazines is now provided with a special latching means. As shown in Figs. 4c and 5, this latching means comprises a for ward plate 56 on each magazine. This plate extends the full width of the magazine, and is hinged on laterally projecting pins 57 secured in the side frame of the magazine. The upper edge of the latching plate has secured thereto, a spring 58 which tends to hold the upper end of the plate retracted, thus throwing the lower hooked end 59 thereof forwardly, releasing the matrices 60 from the position shown in Fig. 6. To latch the plate 56 to prevent the feeding therefrom of the matrices, two cam shaped latch members 61 are pivoted upon a bar 62 on the upper face of the magazine. The two latches 61 are connected for operation together by means of a sliding bar 63 on the lower side thereof to which said latches are secured by said screws 64. A spring 65 is secured between the latch members at 66 to the frame of the magazine, the other end being secured to the inner side of one of the latch members 61. This tends to hold the latch members in position to retain the latching plate 56 in locked position. hen the magazine is introduced into operative position to feed the matrices to the type setting machine, an attachment is provided at the forward end of the magazine frame 3 to operate the latching mechanism. This attachment comprises brackets 65' and 66' on the forward end of the frame. Said brackets have upwardly extending portions on each side of the magazine. A guide member 67 adjacent the bracket 66 guides the magazine into .its seat ready for operation. The bracket member 66" isprovided with-a horizontal slot 68 in which is slidable a re leasing plate 69 to-which is fixed an adjustingdevice70 to limit the movement of said releasing plate in one direction. The bracket 65' is also provided with a slot to receivethe-otherend ofrtheplate 6.9. Said.

plate is cut away centrally at 71 to allow theoperation of the latching plate 56. The rearward side has alug 72 to contact with the end of the latching bar 63 whereby said bar and the latches 61 thereon may be moved laterally when said plate 69 is operated.

The plate 69 is held in a position to release the latches and the latching plate 56 by means of arm 73. Said arm is a curved arm pivoted upon the escapement rod'bracket at 7 1. Its lower end is extended laterally and curve-d to contact with and assist in the operation of a latching lever 75, also pivoted on the escapement rod bracket at 76. An operating lever 77 is pivoted at 78 on the rod bracket, and is connected by means of a link 79 to the lever 75. A slot 80 in said link allows a vertical play of the pin 81 on said link relative to said lever in an obvious manner. The lever 73 is moved into position to unlatch the magazine locking means by a pawl 82 pivoted upon the escapement rod bracket and having a forward cam shaped end 83 bearing against the side of the arm 73. The pawl 82 is raised or lowered to govern the operation of the arm 73 by means of a curved link 84 connecting said pawl with the operating lever 77 at a point 85. It will be thus noted that the spring 65 will tend to throw the latches 61 into locked position, but these latches may be moved and retained in unlatched position shown in Fig. 5 by. the arm 73 engaging with the plate 69 to force the plate and the latches 61 laterally on the magazine to release the latching plate. When the lever 77 is thrown upwardly into dotted line position, as shown in Fig. 5, the action of the spring 65 will move the plate 69 and the arm 73 to one side, thus locking the magazine automatically.

The latching arm7 5 previously referred to, is part of a mechanism operating as a safety device to prevent the movement of the lever 31 to raise. and lower the elevator when the magazine is unlatched so as to release the matrices. This guards against theremoval of the matrixmagazines while the matrices are free to fall out of position therein. The safety mechanism consists of a pivoted cam plate 86 secured centrally to a lug. 87 upon the escapement rod bracket. Said cam plate has a beveled rearward face 88 against which the latch 75 will hear.

The cam plate is held pressed toward the bracket by means of a tension spring 89 connecting said cam plate with the escapementrod bracket. On the lower side of the cam plate is a lateral bracket pin 90 hearing against the forward side of a dog 91 pivoted at 92 to the operating lever 31. When held in locked position, the dog 91 is" retained below the shoulder, 93 onthe lug; 67., thus; preventing the. upward i movement of the arm 31. When the lever 77 is raised into elevated position the cam plate 86 is allowed to be drawn inwardly at the upper end, thus throwing the retaining pin 90 upwardly and allowing the dog 91 on the lever 31 to drop by gravity outwardly beyond the shoulder 93 whereby the lever may be then moved as desired. This assures that the lever 77 must be in elevated position allowing the magazine to be locked before the elevator starting the magazine may be moved. When the lever 7 7 is thrown downwardly, it will force the forward end of the lever 75 inwardly against the cam plate 86, thus throwing the dog 91 into locked position, as shown in Fig. 5.

I11 the operation of this device, the magazine may be elevated and thrown in the rack 6, and another magazine may be received on the elevated rack, and moved into operative position in the manner described, and it will be noted that safety devices are provlded whereby accidents may be positively avoided and the operation of the mechanism made practically fool proof. Thus the operating lever cannot be raised until the magazine is locked. Also the elevator cannot be moved until the latching plate 56 on the magazine is locked, and the elevator cannot be moved vertically until the operating lever is back in its normal position.

In moving the magazines from the elevator rack to the storage rack, the latching members upon the storage rack will not be released until the engaging fingers 51 are in position to receive-it. All of these devices serve to make the operation of the device safe, and proof against accidents. The levers by which a movement of the different parts of the mechanism are accomplished are closely adjacent the hand of op erator and will enable him to change one magazine for the other in a very. shortspace of time without moving from his seat.

The storage rack is shown as accommodating three magazines, but it will be obvious that any suitable number of storage chambers may be arranged within the rack, and the-elevator and cooperating parts may be arranged to accommodate the additional storage chambers. It is also to be noted, as previously mentioned, that only one escapement mechanism is necessary to accommodate any desired number of magazines. Further objects and advantages of myinvention will be apparent to those skilled in the art without further description.
